The work that the members of your small family are doing in spreading the Cause and infusing its divine spirit among the people you meet, is a fact that no one familiar with your life can deny ... In time you will see how abundant the fruit of your services will be. It is not sufficient to number the souls that embrace the Cause to know the progress that it is making. The more important consequences of your activities are the spirit that is diffused into the life of the community, and the extent to which the teachings we proclaim become part of the consciousness and belief of the people that hear them. For it is only when the spirit has thoroughly permeated the world that the people will begin to enter the Faith in large numbers. At the beginning of the spring only the few, exceptionally favoured seeds will sprout, but when the season gets in its full sway, and the atmosphere gets permeated with the warmth of true springtime, then masses of flowers will begin to appear, and a whole hillside suddenly blooms. We are still in the state when only isolated souls are awakened, but soon we shall have the full swing of the season and the quickening of whole groups and nations into the spiritual life breathed by Bahá'u'lláh.
